I’ve made some major renovations to the site. Please pardon its appearance while documents are reattached, broken links are corrected, and images are restored.
I originally created this key for my own personal use in order to update the fantastic keys from Goulet and Huber’s 1993 classic, “Hymenoptera of the World,” which is widely considered by entomologists to be the “wasp bible”. I’ve made a number of updates to the key in accordance with a more modern taxonomic scheme; these changes are all indicated in the introduction. Figures have also been modified to include color indication of key features. This version of the key is restricted to families of the eastern United States, as that is where the vast majority of specimens I work with are collected from. The key is best viewed printed, as the corresponding figures for each couplet appear on the adjacent page, which allows for more flexible use of the key. This version was last updated in January of 2020.
This project is the result of an independent study that sought to use digitized museum data to generate high-quality occurrence-based species checklists. The checklist is accompanied by a key to apoid wasp genera of Ohio based upon the species records in the aforementioned checklist. 137 species in 50 genera and 3 families are included.
Abstract: Digitized museum records of wasps of the hymenopteran superfamily Apoidea were compiled and analyzed to obtain a count and list of species occurring in Ohio. A checklist including all apoid wasp species reported in Ohio is given. A key to included genera is also given.
This project was originally intended to serve as a proof of concept for a unified, updatable set of keys for insects over a large geographical range. Keys to the genera of sawflies and woodwasps of the eastern United States are given, and species keys are given for particularly-small taxa. Small profiles of taxon diversity, biology, and identification are also given. A checklist of genera is provided at the end.
The project is still in its early stages; version 1.0 lacks numerous components, but otherwise comprises a complete set of keys to all established symphytan genera at the time of publication. Planned future updates are included in the article.
A field-guide-style article detailing the single anaxyelid species and fifteen cephid sawfly species known in the continental United States. Keys to species, species range information, and a number of other details are given. A sample entry is given below. Last revised 18 September 2019.
As part of my undergraduate work in entomology, I have begun learning the essential skill of specimen imaging. This page catalogs a selection of specimens I’ve photographed using a Canon SLR lens, two external flash modules, a light filter device, motor-powered camera stepping, and use of PhotoShop, Lightroom, and Zerene image stacking software.
